Hi hope this is posted in the right area, if not Mods please move it to correct section. need a bit of feedback/help from members with experience on A4. im looking to purchase A4 2010 onwards..my preferred model is 2.TDI SLine.. my previous was 330d Msport and previously M5.(was on the verge of bankruptcy) read lot of feed back on the 143 v 170 bhp, most fingers are pointing towards 143 better then 170...not much great difference on power ,more economical on MPG.. any opinions or experiences ? is manual better or auto? I've noticed some with many buttons around the gear lever console in a u form. What are these for? are all S Line standard specs across the models or do they vary and any extras I should consider. finally I believe these cars are stop/start button technology, unfortunately my previous had a flawed in this and went AWOL..so do I need to be aware of security issues in this and upgrade to a more high tech system.my insurers are not interested anymore in high performances due to me moving around a lot of job and to be honest I don't have interest in them much as I never really get full power out of them.. sorry guys I may sound a bit of boring but I think I've had enough of bimmers .2 to be precise..so its the end for them.. Audi is a new experience for me, they do look smart.so going shopping over weekend ..
